• Core function: The turn signal lamp module is used to indicate the turning intention of the vehicle, and remind other road users by flashing alternately in light and dark, thus improving driving safety.
• Components: including turn signal, flash relay (flasher), turn switch and control circuit. Some models are integrated with MCU (micro-controller) to realize intelligent control.
• Workflow: the driver operates the steering switch → the signal is transmitted to the flasher → the current is controlled to be on and off → the turn signal flashes periodically.
• Modularization trend: Modern models mostly adopt integrated modules, which integrate the control circuit with LED light source to reduce the complexity of wiring harness.
• Tool support: use OBD diagnostic instrument to read fault codes, and some models support turn signal module self-diagnosis.
